The wavelength at which the peak of intensity of blackbody radiation occurs

A Increases with increase in temperature
B Decreases with increase in temperature
C Is the same at all temperatures
D Does not follow any pattern as temperature changes

Correct Answer: Decreases with increase in temperature

According to Wien’s displacement law, when the temperature of a blackbody radiator increases, the overall radiated energy increases. Wavelength of maximum emission from a blackbody is inversely proportional to its temperature. Shorter-wavelength (higher-frequency) light corresponds to higher-energy photons.
